BALL-COCK.

Specification of Letters Patent.

Patented Nov. 26, ttt.

Application filed June 27, 1911. Serial No. 635,687.

To all whom 'it may concern:

Be itknown that I, JonN L: H'Aeun, a citizen of the United States, ofMinneapolis,

' Hennepin county, Minnesota, have invented inat'ter (.lescribed andparticularly pointed:

out in the claims.

11i `the accompanying drawings forming part of this specification,Figure l is` a detail sectional View of a ball coek illustrating myinvention, Fig. 2 is a sectional view on the line .fr-a: of Fig. l,Showing the manner of mounting the float and the means for adjusting it,Fig. 3 a side elevation o1" the ball cock.

ln the drawing, 2 represents a easing having anintake pipe 3 and adischarge pipe 4. Upon this easing a plat .3 .is mounted,

' secured by suitable means, such as screws 6 and having an annularflange 7 adapted to bear on the edge of a diaphragm S and Substituting anew one in place of it.

secure it upon its .seat 9 This diaphragm is capable of movement to openor close the intake opening provided in the pipe ll)7 which isconcentric with the pipe The pipe l0 preferably has each' end threadedand provided Withla seat lt to receive the to remove it from the casing,for the, purpose of reversing't-he ends of the pipe or As stated, thepipe 10 listlureaded at both ends and each end has'a valve seat, so thatWhe'n one end becomes Worn or pitted the pipe may be turned end for endand used again.

v This arrangement of thepipe, which may have a seat at both ends or atoney end only, allows its removal from the casing when the supply pipeis detached without disturbing the valve or any ot the connections atthe top ot' the valve casing. The insertion of the pipe into the easingand itsl removal therefrom is' accomplished entirely through theunderside of thevalve casing. A plunger lf3 has a lower end l-l adaptedto bear on the diaphragm and torce it down upon the .seat provided atthe upper end ot' the pipe l0, thereby shutting oil the .tow of waterthrough the intake pipe. Vhen the plunger is raised7 the pressure ot theWater will lift the diaphragm and the water will tiow into the (.-asingand through the pipe 4 into Vthe tank.

For the purpose of raising and loweringl the plunger 13 l provide arecess l5 in its side wall with shoulders 16 tor-ined in the plungerabove and below the recess. These shoulders have, curved faces, asplainly indicated in Fig. l. The plungeril has bearings in the cap andin standards 1T that extend upwardly from said cap and on each side ofthe recess l5. A rock shait 18 has bearingsl at each end in thestandards 17 and is provided with a Acentrally arranged, double cranklil that is adapted to slip into the notch la when the parts areassembled. The shalt lo is held in place by a cotter pin E2() and oneend ot the shaft recessed at Q1 to allow said end to pass the plunger125 and be inserted endwise into itsl bearings in the standards. 'lhedouble crank may be polygonal in cross section, as shown in Fig. t, orcircular, and it is prevented trom passing outy oit the recess inthe'rocking of the shaft 1S by the engagement of the shaft onl each sideof the ress with the curved shouldersI or steps 1(3. these stops aredirectly in the path ot the shaft 18 at each end ot the crank lt) andpositively prevent rotation of the shaft' to such an extent that/thecrank 19 will be rolled out ot' its recess. A socket Q2 is provided inone end of the shaft to receive a rod 23 carrying the float Qland saidrod is locked by n1 xans ot' a set screw 25. The rise and tall of waterin the tank will cause the oscillatioiroin the rod 23 in the usual wayand the rocking ol the shaft 18 and the movement of he plunger intoopening and closing position.

l claim as my invention l. A ball cock comprising a casing having leointake and discharge pipes, a plunger having a seat in said casing andprovided with a transverse recess, a rock shaft having a crank fittingWithin said recess, said plun ger also having a longitudinal recessforming a shoulder therein at one side of said transverse recess, saidshaft having a part to enter said longitudinal recess and engage saidshoulder to limit the 'rot-ary movement of said-shaft in both directionsand thereby preventing said crank from passing out of said transverserecess.

2. A ball cock comprising a casing having intake and discharge pipes, avalve plunger having a seat in said casing and provided with atransverse recess, a rock shaft having a double crank fitting Withinsaid transverse recess and adapted to raise and lower said plunger whensaid shaft is rocked, said plunger also having curved shoulders formedtherein and said shaft having portions to engage said shoulders andlimit the rotary movement of said shaft in both directions, and a floatcarried by said shaft.

3. A ball cock comprising a casing having a discharge pipe, a supplypipe having one end threaded into said casing, a valve 1nounted in saidcasing, a tube having one endy mounted in said casing and provided witha valve seat at. -that end contiguous to said valve, the other en d ofsaid tube projecting outside said casing and extending into saidsupplypipe and having a surface adapted to receive' a Wrench, theseparation of said` supply pipe from said casing allowing access to andremoval of said tube Without removing said valve.

4. A. ball cock comprising a casing having a discharge pipe, a supplypipe* threaded into said casing, a tube threaded at each end andprovided with a valve seat at each end and mounted at one end in saidcasing with the valve seat at that end contiguous to said valve, theother end of said tube depending Within said supply pipe outside saidcasing 'and having aA surface outside said Icasing adapted to receive aWrench When said supply pipe is disconnected from said casing, wherebysaid tube may be removed or turned 'end for end in said casing withoutreversing said valve.

5. A ball cock comprising a casing having intake and discharge pipes, avalve having a seat in said casing, the stein of said valve being'provided With a transverse notch or recess, a

shaft having a double crank and bearings therefor on each side of saidrecess, the crank of said shaft fitting the notch of said stem andv1having only a slight clearance therein, one end of said shaft havinglongitudinal recesses to allow the insertion of said shaft endwise intoits bearings and through the notch in said stein, and means securingsaid shaft in said bearing.

Invvitness whereof, I have hereunto set my hand this 10th day of June1911.
